Quantitative comparison of hair growth. The hair growth area was scanned and measured with Image J. The value is represented as the percentage of the hair growth area relative to the shaved area. The average value is shown, with error bar indicating standard deviation. The calculations excluded the highest and lowest values in each group. Statistical analyses were performed in comparison with the vehicle-treated control group (* p < 0.05; ** p < 0.01; n = 3).
